Description

The present invention vigorously moves a moving side member such as a drawer portion of OA equipment, a placement plate portion such as furniture, and a slide shelf such as a display shelf to a fixed side member of the main body such as OA equipment, furniture, and a display shelf. In order to prevent the moving side member from bouncing off from the fixed side member during transportation, earthquake, etc., the moving side member is retracted from the pulled out state (sliding state) to the storage position (final) Even if it is not completely moved to a predetermined position), when it is stored to a certain position, it will be automatically pulled into the fixed side member and the stored state will be maintained, and when the holding state is released, the moving side member The present invention relates to a sliding device for a moving member having both an automatic extrusion function for automatically extruding to a predetermined position.

When the moving side member such as the mounting plate is stored in the stationary side member such as the furniture body, if the moving side member is stored vigorously, the moving side member may not be completely stored or moved due to rebounding during storage. The side member may not be completely stored from the beginning, which causes inconvenience during transportation of furniture and during an earthquake.
In order to solve this problem, a sliding force adding member attached to the moving side member and a sliding force passive member attached to the fixed side member corresponding to the sliding force adding member are provided. When the member approaches the final predetermined position with respect to the fixed side member, the sliding force passive member has a pressing mechanism that elastically presses a part of the sliding force passive member. There is provided a slide rail provided with a pull-in function, which is provided with a guide inclined surface that changes the pull-in force in a direction to be a final predetermined position with respect to the fixed side member. (For example, refer to Patent Document 1.)

In this case, since the sliding force passive member is configured to be attached to the storage side end of the moving member together with the sliding force adding member, the sliding force passive member is configured to be extremely short compared to the sliding distance of the moving member. The Rukoto.
Therefore, the distance between the pull-in start position and the pull-in end position is shortened, and a preferable pulling effect is obtained such that the pulling is suddenly performed, or a pulling force more than expected is required to pull out the stored and held moving side member. I couldn't.

On the other hand, devices that are often used with both hands closed, drawers that do not have a puller for design reasons, etc., release the holding state from the holding state at the final predetermined position, or once The push-in operation is followed by a push-out function that automatically pulls the drawer out to a predetermined position. A fixed rail is attached to the movable rail with a pulley mechanism so that it can move in the longitudinal direction of the fixed rail. One end of a wire wound in a U-shape around the pulley of the mechanism is attached to one end of the moving rail, and the other end is attached to one end of the stationary rail, and the pulley mechanism and the other end of the stationary rail are There is provided a structure having a tension spring in between. (For example, refer to Patent Document 2.)

In this case, the wire, the pulley mechanism, the pulley mechanism, and the tension spring are all disposed between the fixed side rail and the moving side rail.
For this reason, in the process of assembling the slide rail main body composed of the fixed side rail and the moving side rail, a wire, a pulley mechanism, and a tension spring have to be incorporated in advance, resulting in a problem that production efficiency is very poor.
Further, when a failure occurs in the wire, pulley mechanism, and tension spring, since the failure is incorporated in the inside, only the failed portion cannot be replaced, and the entire slide rail needs to be replaced, resulting in high costs.

On the other hand, in particular, high-quality OA equipment (particularly copying machines) or high-quality system kitchens, etc. have been required to have high functions in each part in order to bring out a high-class feeling.
For example, there has been a strong demand for a paper tray in a copying machine and a drawer in a system kitchen to have both an automatic drawing function and an automatic extrusion function.
However, since the automatic pull-in function and the automatic push-out function have contradictory movements, electrical equipment using a motor was provided, but it was very expensive and had problems with repairs at the time of failure, etc. .

The end portion rotates in a direction away from the fixed member 1, and the pull-in guide path 52 is inclined in a direction away from the fixed member 1 at a steep angle from the beginning.

Therefore, even when the elastic pressure contact force of the rotating roller 814 is the same, the rotating roller 814 (moving side member 203) is automatically and rapidly drawn in the storing direction, and at the same time, the rotating roller 814 is connected to the drawing guide path 52. It moves to the continuous part of the conversion guide path 54 and the extrusion guide path 55 by the inertial force from the rear end of the conversion guide path 54 side. (State shown in FIG. 7)
At this time, when the end of the pull-in guide path 52 on the side of the conversion guide path 54 is away from the end of the push-out guide path 55 on the side of the conversion guide path 54, the end of the pull-in guide path 52 on the side of the conversion guide path 54 The rotating roller 814 moves to the end of the pushing guide path 55 on the conversion guide path 54 side so as to collide instantaneously due to the elastic force of the projectile 811, so that an unpleasant collision sound is generated and unnatural. However, since the guide rotation member 5 is rotated and tilted, the end of the pull-in guide path 52 on the side of the conversion guide path 54 is close to the push-out guide path 55, and the rotary roller 814 is pulled in. Smooth movement from the guide path 52 to the push-out guide path 55 does not cause unpleasant collision sound.
Then, in the shortest contracted state of the slide rail 100, the drawer side end of the moving member 2 passes to the storage side of the latching claw 831 of the latch member 83, so that the latch member 83 rotates downward and is latched. At the same time, the rotating roller 814 reaches the storage side end of the continuous pushing guide path 55 from the lower end of the conversion guide path 54.

Then, since the guide rotation member 5 is positioned in a state where the rotation roller 814 is displaced rearward from the end of the pull-in guide path 52 on the conversion guide path 54 side, the guide rotation member 5 is biased by the leaf spring material 503. 11 is rotated counterclockwise in FIG. 11, the inclined contact surface 510 comes into contact with the surface of the drawer sliding path 822 on the drawer side end, and the end of the pull-in guide path 52 on the conversion guide path 54 side It will be in the state which moved to the fixed side rail 1 direction. (State shown in FIG. 12)
Since the push-out guide path 55 is formed so as to be inclined in the pull-out direction away from the fixed member 1, the rotation roller 814 (sliding force adding member 81, that is, the moving side) is generated by the elastic pressure contact force of the rotation roller 814. The member 203) is automatically pushed in the pulling direction, but the locking claw 831 of the latch member 83 is locked to the pulling side end of the moving member 2, so that the moving member 2 (moving member 203, sliding force) The sliding of the additional member 81) stops, and the storage state of the moving member 203 is maintained.

That is, the moving side member 203 is automatically pulled from a predetermined position and then pushed forward, and is held at a predetermined position with a biasing force applied in the pulling direction.
The movement of the moving side member 203 is particularly required for the movement of a paper tray used in a high-quality copier. In other words, in order to store the copy paper in a predetermined position, it is possible to obtain a more reliable and stable stop position by automatically pushing out and stopping the tray from the state in which the tray is once stored. It is.

Next, by operating the release operation part of the latch member 83 provided in the operation part such as a pulling hand formed on the moving side member 203 or the like, the locking state of the locking claw 831 with respect to the moving side member 2 is changed. When released, the rotating roller is caused by the elastic pressure contact force of the rotating roller 814 located at the end of the pushing guide path 55 on the conversion guide path 54 side and the inclination of the pushing guide path 55 in the pulling direction away from the fixed member 1. 814 (sliding force adding member 81, that is, moving side member 203) automatically moves in the pulling direction, reaches the third opening / closing sliding path 823, and stops. (State shown in FIG. 9)
When the moving side member 203 is further pulled out manually, the rotating roller 814 moves the pulling side end portion of the guide rotating member 5 from the pulling sliding path 822 toward the moving side rail 1 (the state shown in FIG. 10). ) It moves to the open / close sliding path 821, and eventually the moving side member 203 is completely pulled out. (The state shown in FIG. 5)
When the rotating roller 814 moves on the pull-out slide path 822, the pull-out slide path 822 is inclined in the same direction as the pull-in guide path 52, so that a pull-out force against the pull-in force is required.
However, the rotating roller 714 moves to the drawer sliding path 822 with inertia force applied by moving the third opening / closing sliding path 823 at the initial stage of the drawer, so that the sliding without any sense of incongruity is performed. Obtainable.

In the embodiment, the sliding force adding member 81 is provided on the moving side, and the sliding force passive member 82 is provided on the fixed side. However, in FIG. By using the moving member 2 of the example as the fixed member, the same effect as in the embodiment can be obtained even if the sliding force passive member 82 is moved together with the moving member.
In the embodiment, the sliding force passive member 82 and the sliding force adding member material 81 are connected to the slide rail 100 via the fixed side connecting seat 202 and the moving side connecting seat 204, but separated from the slide rail 100, You may attach directly to the fixed side member 200 and the movement side member 203.
